Fillet weld connections
A fillet weld is created if the workpieces
are perpendicular to each other. The
weld should be shaped like a triangle
with sides of equal length and a slight
fillet (Figures AC, AD).
Welds on an inner edge
The preparation for this weld joint
is very simply and is carried out for
thicknesses of 5 mm. The dimension
“d” needs to be reduced to a minimum
and should always be less than 2 mm
(Figure AC).

However, it is no longer expedient for
thicker materials. In this case, it is better
to prepare a joint as shown in Figure
AB, in which the edge of the plate is
angled.
AD
Overlap welds
The most common preparation is that
with the straight weld edges. The weld
can be released using a standard angle
weld seam. Both workpieces must
be brought as close to each other as
possible, as shown in Figure AE.
